27-9 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks GPRS/UMTS Networks Working with the GPRS Tunneling Protocol User Plane (GTPU) The GGSN communicates with SGSNs on a Public Land Mobile Network (PLMN) using the GPRS Tunneling Protocol (GTP). The signaling or control aspect of this protocol is referred to as the GTP Control Plane (GTPC) while the encapsulated user data traffic is referred to as the GTP User Plane (GTPU). GTPU is used for transferring user data in separated tunnels for each PDP context. You can configure various parameters for a GTPU using the configuration commands in the Vision client. You can view the configured parameters for a GTPU in the logical inventory. The following topics explain how to work with GTPU in the Vision client: Viewing GTPU Properties, page 27-9 GTPU Commands, page 27-10 Viewing GTPU Properties The Vision client displays the GTPUs in a GTPU container under the Mobile node in the logical inventory. The icon used for representing GTPUs in the logical inventory is explained in NE Logical Inventory Icons, page A-7. To view GTPU properties: Step 1Right-click the required device in the Vision client and choose Inventory. Step 2In the Logical Inventory window, choose Logical Inventory > Context> Mobile > GTPU Container. The Vision client displays the list of GTPUs configured under the container. You can view the individual GTPU details from the table on the right pane or by choosing Logical Inventory > Context> Mobile > GTPU Container> GTPU. Table 27-6 describes the details available for each GTPU. Table 27-6 GTPU Properties in Logical Inventory Field Description Service Name The name of the GTPU service.

27-11 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks GPRS/UMTS Networks Working with Access Point Names (APNs) APN is the access point name that is configured in the GGSN configurations. The GGSN’s APN support offers the following benefits: Extensive parameter configuration flexibility for the APN. Extensive QoS support. Virtual APNs to allow differentiated services within a single APN. The APN that is supplied by the mobile station is evaluated by the GGSN in conjunction with multiple configurable parameters. Then the GGSN selects an APN configuration based on the supplied APN and those configurable parameters. Traffic policing that governs the subscriber traffic flow if it violates or exceeds configured peak or committed data rates. The traffic policing attributes represent a QoS data rate limit configuration for both uplink and downlink directions. Up to 1024 APNs can be configured in the GGSN. An APN may be configured for any type of PDP context, i.e., PPP, IPv4, IPv6 or both IPv4 and IPv6. Many parameters can be configured independently for each APN on the device. They are categorized as given below: Accounting—Various parameters regarding accounting possibilities, such as, charging characteristics, accounting mode (RADIUS server-based accounting, GTPP-based accounting, and so on.) Authentication—Various parameters regarding authentication, such as, protocols used, like, Challenge Handshake Authentication Protocol (CHAP), Password Authentication Protocol (PAP), or none, default username/password, server group to use, and limit for number of PDP contexts. Enhanced Charging—Name of rulebase to use, which holds the enhanced charging configuration (for example, eG-CDR variations, charging rules, prepaid/postpaid options, etc.). IP: Method for IP address allocation (e.g., local allocation by GGSN, Mobile IP, Dynamic Host Control Protocol (DHCP), DHCP relay, etc.). IP address ranges, with or without overlapping ranges across APNs.

27-12 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks GPRS/UMTS Networks Tunneling: PPP may be tunneled with L2TP. IPv4 may be tunneled with GRE, IP-in-IP or L2TP. Load-balancing across multiple tunnels. IPv6 is tunneled in IPv4. Additional tunneling techniques, such as, IPsec and VLAN tagging may be selected by the APN, but are configured in the GGSN independently from the APN. QoS: IPv4 header ToS handling. Traffic rate limits for different 3GPP traffic classes. Mapping of R98 QoS attributes to work around particular handset defections. Dynamic QoS renegotiation (described elsewhere). You can configure the APN parameters using the Vision client. You can view the configured parameters for an APN in the logical inventory. After an APN is determined by the GGSN, the subscriber may be authenticated/authorized with an AAA server. The GGSN allows the AAA server to return Vendor Specific Attributes (VSAs) that override any or all of the APN configuration. This allows different subscriber tier profiles to be configured in the AAA server, and passed to the GGSN during subscriber authentication/authorization. The following topics explain how to work with APN in the Vision client: Viewing APN Properties, page 27-12 Viewing Additional Characteristics of an APN, page 27-16 APN Commands, page 27-21 Viewing APN Properties The Vision client displays the APNs in an APN container under the Mobile node in the logical inventory. You can also view additional characteristics configured on the APN as explained in Viewing Additional Characteristics of an APN, page 27-16. The icon used for representing APNs in the logical inventory is explained in NE Logical Inventory Icons, page A-7. To view APN properties: Step 1Right-click the required device in the Vision client and choose Inventory. Step 2In the Logical Inventory window, choose Logical Inventory > Context> Mobile > APN Container> APN. Table 27-9 describes the information that is available for the APN. The information that is displayed depends on the configuration of the APN. Table 27-9 APN Properties in Logical Inventory Field Description APN Name The APN name. Accounting Mode The accounting protocol in use in the APN. Values are GTPP (GPRS Tunneling Protocol Prime), RADIUS (Remote Authentication Dial In User Service), or None. Selection Mode The selection mode in use in the APN. Selection mode indicates the origin of the requested APN and whether or not the Home Location Register (HLR) has verified the user subscription. L3 to L2 Address Policy The layer 2 to layer 3 IP address allocation or validation policy.
